Y X Domain And Range
You can take a good guess at this point that it is the set of all positive real numbers based on looking at the graph.
Y x domain and range. The domain of the expression is all real numbers except where the expression is undefined. Free math problem solver answers your algebra geometry trigonometry calculus and statistics homework questions with step by step explanations just like a math tutor. D indicates that you are talking about the domain and read as negative infinity to positive infinity is. Use the graph.
Domain of log x x 2. To avoid ambiguous queries make sure to use parentheses where necessary. Domain and range tips for entering queries enter your queries using plain english. Graph x 3 10 10 5 5 according to this graph of the equation we see that the x values continuously increase while y values do the same.
